Good evening, I bought my self my first Inverter rated at 500W which has a peak rate of 1000W (1kW) maximum. Since some devices such as my main computer for one takes 600W, It does not like the modified sine wave. I was wondering if there is a way to somehow 'convert' the modified sine wave to a standard sine wave so that most of my equipment will work. I'm talking about converting it as soon as it comes out of the 'plug' output of the inverter. Can this be done? If so, how? Thanks.
